Official stamps of the Third Reich period are very basic compared to prior periods. The straw hat issues which were predominant during the latter part of the Weimar period were phased out during the early years of the Third Reich. They were replaced with a swastika design that remained in use until the end of the Third Reich period.
In addition, during the Third Reich period, a new design was introduced which was only for use on Nazi Party correspondence. This “Eagle on a Pedestal” design was in use from 1938-1945.
